Absolutely. I used to use a NAS in preference to a USB. So long as you can mount the drive to somewhere in the Vera file system, you are good to go. You just need to set the path in the DataYours device variable LOCAL_DATA_DIR.
I finally get it up and working and it is what I was looking for. The problem was on my NAS side. Once resolved the mount worked as I indicated it above.
@akbooer. In another thread, you provided screen capture showing graphical information using Grafana . I have read all that I could find in the forum and on the net however, I came to the conclusion that unless you are a software developper and welling to write some kind of plugin for Grafana to querry datayours it is not going to work. Am I correct? Did you ever get it to work with whisper? If so how?
Is there an easy way to have a decent graphic engine that would be using the whisper data?
I don’t have anything that runs on the Vera, but I do have a Grafana server for Whisper files which runs as part of openLuup. Actually, it might be possible to run the openLuup server in a minimal configuration on Vera! But is your NAS something which can run other programs? People have certainly run openLuup on Synology servers. All you need is something which can access the Whisper files and which can run Lua (most things can.)
